We report two cases of unilateral upper cervical spinal cord infarction in the territory supplied by the anterior spinal artery. Early nonspecific MRI abnormalities consisted of hypointense T1 signal and hyperintense T2 signal. A late MRI study showed partial decrease in lesion size due to perifocal edema resorption with negative Gd-DTPA enhancement. The presumed cause of infarction was occlusion of a sulcocommissural artery or of the ipsilateral nutrient branch of the spinal artery.
我们报告了两例由脊髓前动脉供血区域发生的单侧上颈段脊髓梗死病例。早期非特异性MRI异常表现为T1信号低、T2信号高。后期MRI研究显示，由于病灶周围水肿吸收且钆喷酸葡胺增强为阴性，病变大小部分减小。梗死的推测原因是沟连合动脉或同侧脊髓动脉营养支闭塞。
